> You got yourself a one-way single-use FTL byte.

But you don’t.

If I have the entangled version of the MEASURED byte and measure, only I know I’ve measured it. The corresponding MEASURED particles on your side still appear fuzzy to you because you haven’t measured them. If you measure them, they will reveal their state which correlates to mine BUT that doesn’t tell you if I have already measured my side of byte or not.

In effect, the heads/tail coin on your side is still spinning even after I have grabbed my side of the tail/head coin.

You may get HEAD as your result but that only tells you that I will get TAIL when I measure on my side, not that I have measured it already.

If you and I agree to measure at the same time, then I will know your state by determining mine but this is the same as knowing your state because I know how a two sided coin works, not FTL.
